The *mode* parameter selects this mode, and an optional *sensitivity* value can be provided. Currently only the spectrum analyser mode uses the sensitivity value. *sesnitivity* is between 0 and 255. *mode* is one of: * LED_NORMAL Green LED = disk activity, yellow = recording, yellow = SPI activity, and red is not assigned yet. * LED_VU Simple 4-bit VU meter of the playing sound. * LED_SPECTRUM This is the clever one. A spectrum analyser display (4 bit of course) of the playing audio. This uses the dsPIC's DSP to do a full FFT of the current block of audio being loaded into the DMA buffers on the fly, and lights the LEDs depending on various threshold levels. ---- Part of: [Arduino Library]Majenko TechnologiesTue, 06 Nov 2012 12:00:12 -0000https://sourceforge.net181254b6db9b810e370a9a3fe425ec17713a568d
